To allwhornitma concern; I V

Be it known t atll, GHAUNCEY B. Fon- WARD, citizen of the United States,res iding at Urbana, .in'the county of Champaign new and usetu'l llm-provements in an Apparatus Adapted to Distill Crude Petroleum, of which the following is a specification,

l /ly invention relates to an apparatus for producing a powerful motor fuel oil from crude petroleum according-to the mode of operation set forth in my application for Letters Patent filed March 16, 1917, Ser al Number 165,595.

In the accompanying drawings, 1g. 1' is a sectional diagrammatic elevation of the apparatus as an entirety and withv the sev-. eral operating parts coupled up in.work1ng..

relations and substantially taithtiil in details to the actual structure Fig. 2 is a longitudinal sectional elevation of n the oil pre-heating units and which is reterred to herein as the secondary heater or pi'eheater in contradistinctionto the primary or lower heater shown in F1g. 1, a portion being broken out at the middle. 1F ig. 3 is an'end elevation of Fig. 2 with the head of'the the oil conducting coils.therein.

My invention comprises a suitable steam boiler, say such as herein shown having connecting tubes 3, and a" drums 2 and superheater therewith comprising a main or primary coil 4 and a secondary or auxiliary coil 5. The live steam leaves the boiler by pipe 9 and flows first to superheating coil 4 and thence to coil 5 by pipe 6, and the said secondary su'perheater or coil 5 is purposely placed in the. heat flue of the boiler where it will receive the most direct heat generated therein, and the steam is dis great length but compactly housed by this arrangement, and the oil flows through the Uhio, have invented certain one of cylinder removed to disclose coils in a continuous stream andv is heated to a ver high temperature without danger of coking or other deleterious efiect, because the flow or the superheated steam through the preheaters is inverse to the flow of the 011." Thus, the steam flows first into the seconda heater 12, where the temperature otthe' oil has been gradually raised to take advantage of, this condition, and the entrance of the steam into cylinder 12 is by i valved pipe 16 and the two discharge nip? f 1 ples. 17 at opposite ends of the cylinder. Thence the steam passes by short pipe or passage 18 into the primary preheater or m cylinder 14, heating the coil 15 and the oil flowing therethrough onits way to coil 13. In this way the cold oil is first subjected to the steam at a lower temperature in cylinder 14: and-then to the steam at a higher temperature in cylinder 12. 1

Finally, the steam is" discharged from cylinder 14 by the pipe 20 and a portion there? of used to operate the oil pump 21, while the balance passes off through pipe 22 to to be used for any and all purposes for which steam is used' about the plant' Pump 21 has a suitable pipe connection 23 with the oil supply tank or source 24 to feed the oil by a pipe 25 intoprimary coil 15, and which connects by elbow 26 with coil 13. I

' When the heated oil passes from the secondary preheater by way of pipe 30 into the separator or still 27, it is exposed tov highl'y-heated steam entering through an injector 32'connected with apipe,33 leading to the main steam supply pipe 10, and the hydro-carbons volatile at that high temperature are converted into vapor without having subjected the oil to sudden contact-with highly-heated metal containers. The residuum deposited in separator 27 is discharged under valve control through a pipe 35 1 while the. volatile hydrocarbons are dis charged through the bathe column 36 and connecting pipe 37 to the condenser 38, thus practically completing the operation.

Using this apparatus, ,both the motor fuel and the residuum are in better condition for all purposes than when separated or distilled by direct heat as is commonly used, and the specific gravity or end point by distillation of the motor fuel oil may be made higher or lower as desired according to the temperatures maintained in the pre- Mill) heaters and still, which can be varied at will by the operator.

What I claim is: 4 1 An apparatus for treating hydrmcarbon. oils, comprising a plural number of openly-connected cylinders adapted to hold separate large bodies of steam, means adapted to discharge a large volume of superheated steam into said cylinders continuously and successively, separate coils of pipe of great length compactly housed within each of said cylinders and successively connected with each other and ada ted to con-c vey an attenuated stream of oil back and forth for great distances through the separate bodies of steam within each cylinder, means adapted to forceia stream of oil continuously through said coils of pipe, afclosed vapor and liquid separating vessel, a discharge connection for the heated oil leading from said coils of pipe into said vessel,

separate discharge connections for the volatilized and liquid separations within said vessel, and means adapted to effect a continuous outflow of the volatilized and liquid separations through said separate discharge connections while maintaining a constantpressure within said vessel.

2. An apparatus for treating hydro-carbon oils, comprising an oil pump, separate sets of compact coils of pipe of great length connected in series with said pump and each other, separate enclosing cylinders for said coils of pipe having open communication with each other and providing separate large steam chambers, means adapted to de- I Cuyahoga, and State of Ohio, this 8th day of June, 1917.
